Mic mod | uSDX+ | 8 Band SDR | SSB/CW QRP HAM Transceiver | Issue with Iambic paddle + MIC resolved

Problem description:
1) CW iambic mode works well when the Speaker-Mic plug remains disconnected.
2) To switch over to SSB, the mode has to be first changed to LSB/USB, before plugging-in the Speaker-Mic.
3) If the Speaker-Mic plug is plugged-in with iambic mode selected, the rig goes into continuous DIT transmission, and then hangs with TX keyed continuously.

Solution:
This video describes the mod/work-around - to enable trouble-free switching between CW iambic and SSB modes without the need to pull-out or plug-in any connector.
Its's a two-step mod.
The first mod is on the main uSDX+ board, and the second mod is on the supplied speaker-mic (that has an LED to indicate TX). If you are supplied with a different speaker/mic, then the second mod may not be necessary.
